“Unfortunately, the Mayor’s policies are having no impact and we must seek a new approach.

“Trust among the black community around stop and search is low.

“With the number of people being patted down for petty drugs offences, when the statistics show the black community is far less likely to be using drugs, it is clear why.

“I do believe, though, there is a desire for increased searches if they focus on knives and not drugs.

“This refocus should be the catalyst for a major overhaul of our approach to knife crime.

“My approach pulls in the best elements of schemes like the one in Glasgow, utilises social media intelligence gathering to prevent knife attacks and calls for a major long-term strategy that could help cut stabbings in the capital by a third.

“With 80 people killed last year, this goes way beyond party politics and I am urging the Mayor to work with me to address the shortcomings in the current strategy.”

Mr Bailey’s report also calls for a five-to-10-year prevention strategy for youth violence.
